Over & Under 3-Phase Monitor

C269-480VAC

The C269 Over & Under 3-Phase Monitor provides essential protection for industrial systems. Operating at 480VAC, this device continuously monitors for critical conditions including high voltage, low voltage, phase loss, and phase reversal. Its precise adjustable ranges, 400-540V for upper limits and 380-460V for lower limits, enable tailored protection against voltage anomalies. An adjustable response time, from 1 to 10 seconds, allows for system-specific reaction delays, preventing nuisance trips while ensuring timely intervention. The automatic reset feature streamlines operations by restoring functionality without manual intervention after fault clearance. Backed by a 5-year unconditional warranty and holding UL Listed & CSA Certified approvals, the C269 offers reliable performance. Its robust design, featuring SPDT 10A output contacts and an expected relay life of 10 million mechanical operations, ensures long-term operational integrity in demanding environments. This monitor is a critical component for maintaining system uptime and equipment longevity.
